The IMA wants its members, who control about 15 per cent of the stock market, to scrutinise Christopher Bailey’s retention award before casting their vote. Creative director Bailey took over from Angela Ahrendts as Burberry chief executive in May.

Bailey is paid an annual £1.1million salary plus annual allowance of £440,000 and pension allowance of 30 per cent of salary. He was also awarded a one-off, performance-based grant of 500,000 shares.

But under two contracts signed before he succeeded Ahrendts, Bailey was granted one-off share awards totalling 1.35 million shares regardless of how Burberry performs. With shares at 1458p, that would be worth nearly £20million.
